A RE-EVALUATION OF NORMAL PULMONARY FUNCTION MEASUREMENTS IN ADULT FEMALE

Abstract
Pulmonary function parameters were investigated in 101 normal females divided into groups of smokers and nonsmokers. Prediction equations were derived for maximal ventilatory volumes, vital capacity, one-second forced expiratory volume, mid-maximal flow rate, and the ratio of one-second forced expiratory volume to vital capacity. These results would predict higher maximal ventilatory volumes than observed by other laboratories. The smoking women were found to have lower mid-maximal flow rates and ratios of one-second forced expiratory volume to total vital capacity. Other values were not affected by smoking.
